National Products v. MagTarget: Consent Judgment & Permanent Injunction in 126 Days
National Products, Corp. (NPI) filed suit against MagTarget, LLC in the Northern District of California asserting five patents covering magnetic mounting and charging case technology against MagTarget’s Magnetic Charging Case product line. The case resolved in just 126 days via a consent judgment that permanently enjoins MagTarget from making, selling, or importing the accused products in the United States — a swift and comprehensive plaintiff-favorable outcome.
Five-Patent Magnetic Tech Assertion Ends in Full Injunction via Consent
National Products, Corp. (NPI), a holder of a significant portfolio covering magnetic mounting and wireless charging case technology, filed Case No. 4:25-cv-04731 in the U.S. District Court for the Northern District of California on June 4, 2025. NPI asserted five U.S. patents — US10389399B2, US9195279B2, US12143141B2, US10778275B2, and US9632535B2 — against MagTarget, LLC’s Magnetic Charging Case product line, alleging direct and contributory infringement. The case was assigned to Judge Haywood S. Gilliam, Jr., with Fenwick & West, LLP representing NPI and Hoge Fenton Jones & Appel, Inc. representing MagTarget.
The litigation concluded on October 8, 2025, just 126 days after filing, through a consent judgment rather than a contested trial or standard settlement. The consent judgment is a court-entered order that carries the full force of a judicial ruling: MagTarget is permanently enjoined from manufacturing, using, selling, offering for sale, or importing the accused products or any products not more than colorably different therefrom, including through U.S. distributors. Critically, neither party may challenge or appeal the judgment, and all of NPI’s claims are resolved with prejudice.
The speed of resolution — four months from filing to final judgment — suggests MagTarget likely concluded early that contesting five patents across multiple technology families carried prohibitive risk or cost. The consent judgment’s explicit language extending the injunction to products ‘not more than colorably different’ signals NPI sought and obtained broad prospective protection, not merely relief tied to the specific accused SKUs. The public record does not disclose any financial consideration, royalty arrangement, or licensing terms beyond the cost-bearing provision, leaving the commercial resolution between the parties undisclosed.

Consent judgment entered: what the permanent injunction means for both parties
A consent judgment is a court order — not just a settlement agreement
Unlike a private settlement, a consent judgment is entered by the court and carries the full enforceability of a judicial decree. Both parties agreed to its terms, but Judge Gilliam’s order means MagTarget’s compliance is now subject to contempt proceedings — not merely contract remedies. The explicit waiver of any right to challenge or appeal removes virtually all post-judgment risk for NPI.
Court-enforceable final orderNPI secures a permanent U.S. injunction across its full patent portfolio
NPI obtained arguably the most commercially significant remedy in patent law: a permanent injunction that extends not only to the named accused products but to any product ‘not more than colorably different.’ This anti-colorable-difference language significantly limits MagTarget’s ability to redesign around the judgment. All claims are resolved with prejudice, extinguishing any future relitigation of the same accused conduct. Each party bears its own costs, which is consistent with a negotiated resolution where NPI prioritized injunctive relief over fee recovery.
Permanent injunction — broad scopeMagTarget accepts a broad U.S. sales ban with no appeal rights preserved
MagTarget’s consent to this judgment effectively bars it from the U.S. market for its Magnetic Charging Case line and any colorably similar successor products. The explicit waiver of appeal rights is unusual and forecloses the standard post-judgment review pathway. The extraterritoriality carve-out — limiting the judgment to U.S. patent law — suggests MagTarget may retain the ability to operate in non-U.S. markets, though any such activity would need independent assessment under applicable foreign law.
U.S. market exit — no appeal pathNPI’s five-patent moat around magnetic mounting tech is now court-validated
A consent judgment entered without substantive invalidity or non-infringement findings does not formally validate the asserted patents — but MagTarget’s decision to forgo any challenge may signal that its counsel assessed the patents as difficult to invalidate. Competitors in the magnetic mounting and wireless charging accessory space should treat NPI’s portfolio with heightened caution: the injunction’s ‘not more than colorably different’ language suggests NPI will aggressively police design-arounds, and the speed of this resolution may embolden further enforcement actions.

Official order — verbatim text
The consent judgment’s operative language is notably expansive: the injunction extends to ‘any other products not more than colorably different’ from the accused products and explicitly captures distribution through third-party U.S. distributors. Crucially, the judgment contains no admission of liability, invalidity finding, or damages award — the absence of these elements is consistent with a negotiated resolution where MagTarget conceded market exit in exchange for avoiding a contested merits ruling. The mutual cost-bearing clause and the extraterritoriality carve-out further suggest this was a carefully negotiated commercial resolution given the force of a final court order.
US10389399B2, US9195279B2, US12143141B2, US10778275B2 & US9632535B2 — magnetic mounting and charging case technology
The five asserted patents — US10389399B2, US9195279B2, US12143141B2, US10778275B2, and US9632535B2 — collectively cover a layered technology stack related to magnetic mounting interfaces and charging case designs for mobile devices. Application dates span from at least 2015 (US14/667564, parent of US9195279B2) through 2024 (US18/638555, parent of US12143141B2), indicating NPI has pursued a sustained prosecution strategy to extend its coverage as the magnetic accessory market evolved. The portfolio’s breadth across multiple application families suggests both foundational and improvement claims are in play.
The commercial context is the rapidly growing MagSafe-compatible and magnetic wireless charging accessory market, where multiple manufacturers compete on thin hardware differentiators. NPI’s decision to assert five patents simultaneously — rather than a single patent — is a deliberate portfolio enforcement tactic designed to maximise invalidity challenge cost and signal the depth of its IP moat. Competitors and new entrants developing magnetic charging cases, mounts, or similar accessories face meaningful freedom-to-operate risk against this portfolio, particularly given the court-validated injunction scope now on the public record.
Should you run an FTO against NPI’s magnetic mounting and charging case patents?
Any company developing, manufacturing, or distributing magnetic charging cases, MagSafe-compatible accessories, or magnetic mounting systems for mobile devices in the U.S. market should treat this consent judgment as a direct signal to conduct a formal FTO analysis. NPI’s five-patent portfolio now carries the weight of a court-enforced injunction, and the ‘not more than colorably different’ language suggests NPI will assert that even redesigned products fall within scope. Hardware startups, OEM accessory makers, and retailers sourcing magnetic charging cases from third-party suppliers are all potentially exposed.
PatSnap Eureka’s FTO Search Agent can map your product’s feature set against the claim language across all five NPI patents simultaneously, identify prosecution history estoppel constraints, and flag continuation applications that may not yet have issued. Eureka’s claim chart generation and prior art search tools can also support an invalidity assessment if you are evaluating whether to challenge any of these patents at the PTAB — particularly the more recently issued US12143141B2, which may face a narrower prior art window.

What this case signals for the magnetic mounting and charging accessory IP landscape
NPI’s swift five-patent enforcement victory sets a clear precedent for how aggressively held magnetic tech IP can be deployed against accessory makers.
Speed and breadth of injunction suggests NPI is in active enforcement mode
A 126-day resolution with a permanent injunction and no-appeal clause is not a typical outcome — it suggests MagTarget assessed the cost and risk of contesting five patents as untenable. Companies operating in the magnetic mounting, MagSafe-compatible, or wireless charging case space should assume NPI is monitoring the market and prepared to move quickly against identified infringers.
The ‘colorably different’ clause creates a long shadow over competitor product design
NPI’s insistence on anti-colorable-difference language in the injunction — and MagTarget’s acceptance of it — means the order is designed to survive minor design modifications. For R&D teams working on magnetic charging accessories, this signals that any product development in this space should be preceded by a thorough FTO analysis against NPI’s five asserted patents and the broader portfolio, not just the specific claims litigated here.
National v MagTarget — key questions answered
The case resolved via a consent judgment entered October 8, 2025, permanently enjoining MagTarget from making, selling, offering for sale, or importing its Magnetic Charging Case products in the United States. All of NPI’s claims were resolved with prejudice. Neither party may challenge or appeal the judgment. Each party bears its own costs and attorneys’ fees.
NPI asserted five U.S. patents: US10389399B2, US9195279B2, US12143141B2, US10778275B2, and US9632535B2. These patents collectively cover magnetic mounting systems and charging case technology for mobile devices, with application dates spanning from approximately 2015 to 2024, indicating a layered prosecution strategy across multiple technology generations.
This clause extends the injunction beyond the specific accused products to any redesigned products that are not substantially different from the accused products. Under Federal Circuit precedent, a product is ‘colorably different’ only if it lacks the features that were the basis of the original infringement finding. This makes it significantly harder for MagTarget to reenter the U.S. market with a redesigned product without risking contempt of court.
No. The consent judgment contains an explicit and mutual waiver of the right to challenge or appeal. Both parties ‘knowingly, intentionally, willingly, and explicitly’ waived these rights. This is a significant departure from a standard settlement agreement and forecloses the normal post-judgment review pathway available in contested patent cases.
No. The consent judgment expressly states it is limited to the scope of U.S. patent laws and has no extraterritorial effect. The parties further agreed that the consent judgment cannot be introduced or used as evidence of infringement or patent validity in any proceedings outside the United States. MagTarget’s ability to operate in non-U.S. markets is therefore not directly affected by this judgment.
